The GIA Male Valve is specially designed for split air conditioning systems and heat pumps, allowing for repeated coupling and decoupling of stop valves without the need for evacuation or refilling of refrigerants. Its innovative design ensures safe, reliable, and efficient operation throughout the system’s lifecycle.
Easy and Safe Coupling: Unique design allows proper connection of stop valves without torque wrenches, preventing accidental uncoupling.
Maintenance-Friendly: Supports repeated coupling and decoupling (up to 75 times) without interruption to refrigerant or system functions.
High Reliability: Industrially manufactured flare connectors minimize assembly errors and leakage, ensuring long-term performance.
Time & Effort Saving: Simplifies component replacement, warranty service, and new installations, reducing technical effort and downtime.
Refrigerant Loss Prevention: Prevents accidental complete loss of refrigerant during improper disassembly or maintenance by non-certified personnel.
Regulation Compliant: Meets European Standard EN 378 for refrigeration systems and heat pumps, and EU Regulation No. 517/2014 regarding maximum permissible leak rates.
Durable Seals: HNBR (Hydrogenated Acrylonitrile Butadiene Rubber) seals provide a wide operating temperature range and excellent chemical resistance to refrigerants and oils.
Precision Connection: Male stop valves feature SAE internal threads for flared joints with pressed-in copper sealing rings; female stop valves come with soldering sleeves for inch-diameter pipes.

Applicable Pipe Types
Suitable for copper, aluminum, and other approved refrigeration pipes. Not recommended for plastic or unapproved metal tubing.
Ensure pipe diameter matches the valve size before installation to prevent loose connections or leaks.
Installation
Release system pressure and ensure no high-temperature liquid or gas remains in the pipes before installation.
Avoid overtightening the valve during connection to prevent thread or seal damage.
Verify that the valve seal materials (CR, HNBR, FKM) are compatible with the refrigerant used (e.g., R410A, R32, R22).
Operation
Supports repeated coupling and decoupling up to approximately 75 times; avoid using excessive force or non-professional tools.
Never disconnect the valve under system pressure to prevent refrigerant discharge and potential injury or environmental hazards.
Maintenance
Periodically inspect the valve seals; replace any worn or leaking seals immediately.
Avoid prolonged exposure to high temperatures, corrosive chemicals, or direct sunlight to extend valve life.
Safety and Environmental Considerations
Wear protective gloves and safety goggles when handling the valve to prevent refrigerant exposure.
Follow local regulations for refrigerant handling and recovery to avoid environmental contamination.
Do not modify or disassemble the internal structure of the valve.
Q1: What refrigerants is the GIA ¼″ male valve compatible with?
A1: The valve is compatible with most common HVAC/R refrigerants such as R410A, R134a, R22, R502, etc. (Please refer to the product specification sheet for the exact list.)
Q2: What is the maximum working pressure?
A2: The valve is designed to handle high working pressures (for example up to approx. 800 psi or higher). (Check the datasheet for your version.) Similar valves list working pressure ~800 psi and burst pressure ~4000 psi.
Q3: Is it compatible with both male and female ports?
A3: This model is designed for a ¼″ male port connection. If you require a female port, please contact us for a matching adapter.
Q4: How do I verify a leak‑tight connection?
A4: After connecting and properly tightening the valve, apply a leak‑detection method such as soapy‑water foam, electronic detector or vacuum hold test. Ensure no bubbles or pressure drop is observed.
